HiLetgo CP2102 USB 2.0 to TTL 5PIN Serial Converter Module With cable for Linux, macOS, Win7, Win8, Win10

This is a great bit of kit. I use these to replace the Prolific USB programing cables supplied with most Chinese handheld radios. There are so many fake Prolific cables out there it's not worth the hassle. So these 2102's were substituted and they work fine, every time.

Worked straight out the packet, Windows 10 installed drivers as soon as I plugged it in, set up my terminal software and I was good to go. Well worth it !!!

Used this to flash tasmota to sonoff. Worked perfectly.

this is a good serial board to get - has clear markings on the pcb

This unit worked perfectly once I found a driver for the Windows 7 64bit computer I used it with. my reason for giving less than optimum rating is that the ebay page relating to the product did not make it clear that a suitable driver would be needed.

Used this on a linux box and got great results with it so no complaints at all.

Great item

Connect my laptop to my raspberry pi Serial connection just fine. Does not have the grunt required to connect to an ESP8266 as i do not have the ability to perform the circutry changes that will allow this: http://www.instructables.com/id/Mod-a-USB-to-TTL-Serial-Adapter-CP2102-to-program--1/ I will just continue to use it as is and program my ESP8266 via my raspberry pi instead

I recently acquired a semi-broken router that has a UART connector on it, and I needed to talk to it. This device makes it easy to talk to anything that has TTL or UART. It's super easy as it's plug and play! Just plug the cables into the right pins on the adapter, then plug it into your computer. It's worked with all of the devices I've tried it with, which makes it super functional. I would definitely recommend this high-quality product to anyone who needs a direct serial connection.

As described

Funciona perfectamente, y ademas tiene 5V y 3V (creo, puede que sean 3.3V, no lo he comprobado) Se conecta perfectamente dando un serial de "0001" en la interfaz USB con el nombre de "CP2102 USB to UART Bridge Controller".

Funziona perfettamente! Ho installato un firmware open-source su un vecchio modem-router brandizzato, sbloccando diverse funzioni e dando nuova vita ad un oggetto ormai inutilizzato e che ora è in salone e funziona perfettamente come access point! Tutto questo grazie a questo oggettino dal prezzo irrisorio. Consigliato!

The clear heat shrink around the pcb extended too far over the usb plug and had to be trimmed back before it would go into the usb port. Once that was done the device was automatically detected and the proper drivers were loaded by the kernel. It worked as expected on a linux machine using: minicom -D /dev/USB0
